VariousElectrical connectorIt is a key component in countless electronic devices, because they can realize and protect the transmission of electrical signals. From connecting key computer components to connecting wires in the cars we drive, they play a wide range of roles, and the applications they serve are also different. Despite the simple design, connectors are usually implemented in complex electrical systems. Therefore, the connector must be durable and reliable, while being easy to assemble and use. Although not all electrical connectors can withstand extreme environments, the large number of connector specifications ensures that suitable variants can be found for a given device.

General Electric Connector

8P8C connector

The 8P8C connector's name comes from the phrase "eight positions, eight conductors." As the name suggests, this small connector has eight possible positions, and each position has a corresponding conductor. It is a modular connector originally used for telephone line applications, but can also be used for various other functions, such as an Ethernet jack. All four sizes of modular connectors are named according to the position they have and the number of conductors, including sizes 4, -, 6-, 8- and 10-. For example, 10P8C will have 10 positions and 8 conductors.

The 8P8C connector itself includes plug and socket connections, with plugs and corresponding sockets. The plug has eight contacts, aligned with the eight wires of the socket, and transmits current through the connector. In addition to being used for Ethernet jacks, 8P8C connectors are also commonly used in computer applications and communication cables.

D type miniature connector

Very similar to the 8P8C connector, D-subminiature connectors are usually used in computer applications, but the capacity is different: they are used as a key port (RS232) on the modem. Despite the term "subminiature", the D-subminiature connector is now relatively large compared to other more modern computer connectors. D-subminiature connectors together with D-shaped metal parts protect the connector and limit its shape. D-subminiature connectors consist of two or more rows of pins (or sockets, depending on the gender of the connector) of different numbers. If there are pins, the connector is a male, called a plug; the corresponding receiving device is called a socket, which houses the contacts that the pins must connect to in order to transmit power. Features related to this variant include the ability to prevent electromagnetic interference.

DC connector

Direct current (DC) connectors provide direct current for a given application, so they must be used carefully to ensure that the device is not damaged. Common types of DC connectors include DC plugs and coaxial DC power connectors, which mainly connect devices to a power source.

USB connector

The Universal Serial Bus connector is a small interface device that can be used to connect more than 127 devices to a computer. Standard laptop computers usually have at least two USB ports to support external connections through USB connectors, while standard desktop computers have four USB ports. Since the USB connector can be inserted and unplugged when the connected device is opened, it is widely used in computer systems, which constantly need to be connected and separated from external devices, which is necessary when transferring data.

As with many connectors, there are multiple USB variants. USB connectors 1.0, 2.0, and 3.0 can be used for high-speed and low-speed connections. USB1.0 models provide keyboard and mouse connections, and USB2.0 provides connections with the same equipment, but at a faster speed.
